Iphone – HTTP Live Streaming, FFMPEG & FFSERVER, and iPhone OS 3


In iPhone OS 3, Apple has introduced HTTP Live Streaming which should allow live streaming of video from the internet. I am currently operating a webcam, which feeds into my server, and is then converted into a flv stream by ffmpeg, and streamed back out using ffserver. Does anyone know how to setup a video stream the iPhone can use using ffmpeg and ffserver? I should be able to re-encode into just about any format on the fly.

You'll need to build a copy of ffmpeg with a version >= e109a29d6ddb02b2dd58c6c385ebec27f2d23b58 (git) or 18793 (svn). Make sure you also specify the --enable-libx264 flag when you're building. Once you've got that up and running, you can do roughly the following:

ffmpeg -i <input video> -acodec libmp3lame -ac 1 -vcodec libx264 -s 320x240 \
       -level 30 -f mpegts - | \
segmenter - 10 test test.m3u8 http://example.com/path/to/your/files/

i.e. Bring an input file or stream into ffmpeg and pipe an H.264 video with MP3 audio into Apple's segmenter. The segmenter spits out segmented video files and M3U playlists pointing to the segmented files. You'd serve the segmented files and playlists via a web server like Apache.

Obviously you'll want to tweak the ffmpeg and segmenter options substantially to get the results you're after.
